所需调用能力：
- image_delivery
运行前提：
- Existing authorized installation with exact binary SHA
- Input is actual JPEG1200x800/RGB with SHA e2923b1662fdf1b3c577d19f4a6b1ee57f6b41a6f4b45c44b2ebc9e3d2e8b97c
- Partial query gaps about cost/region/retention do not become verified; no installation or upload
使用步骤：
- Read actual byte signature and input SHA; preserve original
- ffmpeg -nostdin -hide_banner -loglevel error -n -protocol_whitelist file -i INPUT -vf scale=945:630:flags=lanczos,format=rgb24,pad=1200:630:127:0:white,setsar=1 -frames:v 1 -c:v mjpeg -pix_fmt yuvj444p -q:v 2 -threads 1 OUTPUT
- Decode actual output fully, check1200x630, media,307200B/756000pixel cap, full-frame/padding/no-upscale; on failure retain evidence and stop
- 输入约定
- Exact owned source e2923b1662fdf1b3c577d19f4a6b1ee57f6b41a6f4b45c44b2ebc9e3d2e8b97c; source99659B JPEG even though png filename; no general input substitution
- 输出约定
- jpeg1200x630 contain white; 122351B observed; within307200B. No broader size guarantee.
- 成功检查
- Pillow full decode/pixel access and FFprobe; compare whole source and padding. Exit0 alone is insufficient. No ICC/EXIF/alpha generalization.
- 失败与回退
- Return unknown/conflict, keep original and failure. PNG budget conflict must not be retried automatically or constraints weakened.
